Aspirated stomach acid

I've taken 20 mg. famotadine every morning for years, occasionally 20 mg. at night as well, along with 1 or 2 Rodaids at bedtime. This usually controls my GERD while I sleep but at times I need 4 or 5 more Rolaids in the middle of the night. A few days ago I had a severe nighttime reflux and aspirated enough acid to choke me into an incredible coughing fit. Two days later my lungs started burning, I got moderately nauseous, with fever and chills that lasted two days. I started getting better but now two days later my lungs are beginning to burn again. Can I have gotten some kind of pulmonary infection from aspirating all the acid? Do I need antibiotics or will this probably clear up on it's own?
